Stars know a little something about being idolized—and they'll even admit to a few infatuations of their own. We asked celebrities at the opening of the Tommy Hilfiger flagship store, a party for Curb Your Enthusiasm, and a Cinema Society screening of The Twilight Saga: New Moon whether they had any same-sex crushes.

Many women have an eye for beauty. "I met Julia Roberts for 30 seconds, and it was unforgettable for me," said Audrey Tautou. Katharine McPhee admires Megan Fox: "Physically speaking, she's just perfect." Men go for similar interests or simple proximity. Nick Cannon named Will Smith as his crush: "We work out together in the gym." Jimmy Fallon claimed that he has fielded advances from a fellow talk-show host: "Regis Philbin wants to start a bromance with me. We've got a lot in common—we both like Dean Martin DVDs. I'm down if he wants to do it."
